Nickel organic compositions to improve dyeability of polymers

ABSTRACT

Nickel organic compositions prepared from a nickel salt of a 1,3-diketone of the formula ##STR1## wherein R and R&#39; are independently C 1  -C 8  alkyl; and sulfonyl dialkylphenols of the formula ##STR2## wherein R&#34; and R&#39;&#34; are independently C 1  -C 12  alkyl are used to provide polymer compositions which have improved dyeability after exposure to high temperatures. Preferably, the nickel salt of acetyl-acetone and 2,2&#39;-sulfonylbis-(4-t-octylphenol) are reacted together and the polymer is a polyolefin. Most preferably, the polyolefin is polypropylene.
